Hydraulisch gedämpftes elastisches Lager insbesondere für den Antriebsmotor in Kraftfahrzeugen Hydraulically damped elastic bearing, especially for the drive motor in motor vehicles

Die Erfindung bezieht sich auf hydraulisch gedämpfte elastische Lager insbesondere für den Antriebsmotor in Kraftfahrzeugen, mit einem von gummielastischen Federelementen abgedeckten und durch eine starre . Trennwand in zwei mit einer Dämpfungsflüssigkeit gefüllte wechselweise voiumenveränderliche Kammern unterteilten Gehäuse, wobei die Trenn wand eine über einer Ausnehmung mit Axial spiel eingespannte, einen verengten überströmweg für die Dämpfungsflüssigkeit begrenzende biegsame Membran aufweist.The invention relates to hydraulically damped elastic bearings especially for the drive motor in motor vehicles, with one of rubber elastic spring elements covered by a rigid one. Partition wall divided into two alternately variable volume chambers filled with a damping fluid, the partition wall has a flexible membrane that is clamped over a recess with axial play and delimits a narrowed overflow path for the damping fluid.

Der geringfügige Freiweg der Membran in solchen Lagern, der sich üblicherweise in Größenordnungen von nur wenigen Zehnteln Millimetern hält, hat zur Folge, daß zu der Federbewegung zunächst ein verhältnismäßig weiter überströmweg zwischen den beiden Teilkammern für den Druckausgleich zur Verfugung steht und erst mit dem Anliegen der Membran die Drosselwirkung einsetzt. Unter wechselnden Prüfbedingungen und auch im praktischen Einsatz zeigten die Lager in bestimmten Frequenz- und Amplitudenbereichen verschiedentlich die Neigung zu lästigen Geräuschentwicklungen. Es ist die Aufgabe der Erfindung, das akustische Verhalten der Lager ohne Beeinträchtigung der erwünschten Dämpfungswirkung zu verbessern.The slight free travel of the membrane in such bearings, which is usually on the order of only a few tenths of a millimeter holds, has the consequence that to the spring movement initially a relatively further overflow path between the two sub-chambers for the Pressure equalization is available and the throttling effect only begins when the diaphragm is in contact. Under changing test conditions and in practical use, the bearings sometimes showed a tendency to produce annoying noise in certain frequency and amplitude ranges. It is the object of the invention to improve the acoustic behavior of the bearings without impairing the desired To improve the damping effect.

Nach der Erfindung ist in Lagern der eingangs geschilderten GattungAccording to the invention is in camps of the type described above

der Innenrand der Ausnehmung in der Trennwand mit in gegenseitigen Winkel abständen über ihren Umfang verteilten, den Randwulst der Membran übergreifenden Ausbuchtungen ausgebildet, wobei die Ausbuchtungen zweckmäßig im wesentlichen als Kreisabschnittsflächen, z.B. als Halbkreisflächen gestaltet sein können. In Weiterbildung der Erfindung empfiehlt es sich, die zwischen den Ausnehmungen zahnartig nach innen vorspringenden Randteile der Ausnehmung beiderseits in Richtung gegen die Membrane abzubiegen.the inner edge of the recess in the partition wall with in mutual At angular intervals distributed over its circumference, bulges overlapping the edge bead of the membrane are formed, the bulges expediently essentially as circular segment surfaces, e.g. as Semicircular surfaces can be designed. In a further development of the invention, it is advisable to follow the tooth-like between the recesses to bend inwardly protruding edge parts of the recess on both sides in the direction towards the membrane.

Mit der erfindungsgemäßen Gestaltung der Dämpfungsvorrichtung gelingt es, die bisher als unvermeidlich hingenommenen Geräusche der schwingenden Lager auch in den kritischen Bereichen praktisch vollständig zu unterdrücken. Diese günstige Wirkung ist auf Verbesserungen in dem Strömungsfluß im Einspannbereich der Membran,zurückzuführen. Mit der aufgefundenen Lösung stützt sich die Erfindung auf die Erkenntnis von der Bedeutung der Membran-Anlageflächen in der dem Randwulst zugeordneten Umfangszone der überdeckten Ausnehmung in der Gehäuse-Trennwand als ursächlich für die Geräuschentstehung. Die daraus gefolgerte Annahme von einer durch das wechselweise Verdrängen von Dämpfungsflüssigkeit unter dem Einfluß höherer Schwingungsfrequenzen hervorgerufenen Verhärtung hat sich in der praktischen Ausführung des Erfindungsgedankens als richtig erwiesen.With the design of the damping device according to the invention succeeds it, the noises of the vibrating bearings, which were previously accepted as inevitable, practically completely, even in the critical areas to suppress. This beneficial effect is due to improvements in the flow flow in the clamping area of the membrane. With the solution found, the invention is based on the knowledge of the importance of the membrane contact surfaces in the edge bead assigned peripheral zone of the covered recess in the housing partition wall as the cause of the generation of noise. The inferred assumption of one by the alternating suppression of Damping fluid caused hardening under the influence of higher oscillation frequencies has proven itself in practical implementation of the inventive idea proved to be correct.

Zum Verdeutlichen der Erfindung ist ein Ausführungsbeispiel in der Zeichnung schematisch dargestellt. Es zeigen:To illustrate the invention, an exemplary embodiment is shown in FIG Drawing shown schematically. Show it:

Fig. 1 ein Motorlager im Querschnitt und Fig. 2 eine Einzelheit aus Fig. 1.1 shows an engine mount in cross section and FIG. 2 shows a detail from FIG. 1.

Das gezeichnete Lager ist zweigeteilt aus einem topfartigen GehäuseThe bearing shown is divided into two parts, consisting of a pot-like housing

3 und einem dieses nach oben abdeckenden und mit einem Anschlußteil3 and one this upwards covering and with a connector

4 haftend verbundenen kegel stumpfförmigen Gummi-Federelernent 5 aufgebaut. Das Gehäuse 3 ist in seinem unteren Teil mit mehreren Entlüf-4 adhesively connected conical frustum-shaped rubber spring element 5 constructed. The housing 3 is in its lower part with several vent tungslöchern 13 versehen und wird durch eine dichtend in eine flanschartig umgebördelte Randeinfassung eingespannte biegsame Membran 6provided with holes 13 and is sealed by a flexible membrane 6 clamped in a flange-like beaded border

nach außen abgeschlossen. Mit Hilfe einer fest in das Gehäuseunterteil eingesetzten Kopfschraube 23 kann das Lager an einem nicht gezeichneten Karosserieteil befestigt werden, während der Anschlußteil 5 zum Anbringen an einer ebenfalls nicht weiter dargestellten Motorhalterung vorgesehen ist und zu diesem Zweck eine Kopfschraube 15 trägt. Eine in die Randeinfassung des Gehäuses 3 eingesetzte Trennwand 7 teilt den Gehäuseinnenraum zwischen dem Federelement 5 und der Membran 6 in eine obere und eine untere Kammer 8 bzw. 9 auf, die beide mit einer Dämpfungsflüssigkeit vollständig angefüllt sind.closed to the outside. With the help of a firmly in the lower part of the housing used head screw 23, the bearing can be attached to a body part, not shown, while the connection part 5 to Attachment to a motor mount, also not shown is provided and carries a head screw 15 for this purpose. A partition 7 inserted into the edge of the housing 3 divides the housing interior between the spring element 5 and the membrane 6 into an upper and a lower chamber 8 and 9, both of which are completely filled with a damping fluid.

Die Trennwand 7 besteht im wesentlichen aus zwei identischen metallischen Ringelementen, die in der gezeichneten Einbaulage eine die konzentrische Ausnehmung 17 überspannende biegsame Membran 10 mit geringfügigem Axialspiel beweglich an ihrem Randwulst zwischen sich einschließen. Die Halterung der Membran 10 bildet gleichzeitig einen ständig offenen wenn auch verengten Überströmweg zwischen den beiden Kammern 8 und 9, der mit dem Anschlagen der Membran an eines der Ringelemente 7 unter der Wirkung eines Druckunterschiedes nach Aufbrauchen des verfügbaren Freiweges eine weitere Verengung erfährt. Die die Ausnehmung 17 begrenzenden Randflächen der Ringelemente 7 sind gemäß der Draufsichtsdarstellung in Fig. 2 einer Innenverzahnung vergleichbar mit einer Folge von halbkreisförmigen Ausbuchtungen 27 gestaltet, so daß die Membran 10 praktisch nur mit den zwischen jeweils benachbarten Ausbuchtungen nach innen vorspringenden Randteilen 37 der Ringelemente in Berührung kommt. Wie es die Querschnittsdarstellung in Fig. 1 erkennen läßt, sind die Randteile 37 beiderseits der zusammengesetzten Trennwand wenigstens teilweise in Richtung gegen die Membran abgebogen.The partition 7 consists essentially of two identical metallic ones Ring elements which, in the installation position shown, have a flexible membrane 10 spanning the concentric recess 17 with slight Enclose axial play movably at their edge bead between them. The holder of the membrane 10 simultaneously forms a constantly open albeit narrowed overflow path between the two chambers 8 and 9, which occurs when the membrane hits one of the Ring elements 7 experiences a further narrowing under the effect of a pressure difference after the available free path has been used up. The edge surfaces of the ring elements 7 delimiting the recess 17 are, according to the top view representation in FIG. 2, of internal teeth comparable to a series of semicircular bulges 27 designed so that the membrane 10 practically only with the inwardly projecting edge parts between adjacent bulges 37 of the ring elements comes into contact. As the cross-sectional view in FIG. 1 shows, the edge parts 37 are on both sides the composite partition at least partially bent towards the membrane.

Der Durchmesser D der Ausnehmung - zwischen den vorspringenden Randteilen 37 gemessen - ist kleiner als der mittlere wirksame Durchmesser dm des Gummi-Federelementes 5. Für die Funktionstüchtigkeit der neuartigen Drosseleinrichtung hat sich als besonders günstig herausgestellt, das Maßverhält
größer als 0,5 zu wählen The diameter D of the recess - measured between the protruding edge parts 37 - is smaller than the mean effective diameter dm of the rubber spring element 5. The dimensional ratio has proven to be particularly favorable for the functionality of the novel throttle device
